The ShortPixel Image Optimizer – Optimize Images, Convert WebP & AVIF plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'shortpixel_ajaxRequest' AJAX action in all versions up to, and including, 6.3.4. This makes it possible for authenticated attackers, with Contributor-level access and above, to export and import site options.
